CSSValue

{{APIRef("CSSOM")}}{{Deprecated_Header}}

The CSSValue interface represents the current computed value of a CSS property.

[!NOTE] This interface was part of an attempt to create a typed CSS Object Model. This attempt has been abandoned, and most browsers do not implement it.

To achieve your purpose, you can use:

• the untyped CSS Object Model, widely supported, or
• the modern CSS Typed Object Model API, less supported and considered experimental.

Instance properties

• {{DOMxRef("CSSValue.cssText")}} {{Deprecated_Inline}}
  • : A string representing the current value.
• {{DOMxRef("CSSValue.cssValueType")}} {{ReadOnlyInline}} {{Deprecated_Inline}}

  • : An unsigned short representing a code defining the type of the value. Possible values are:

    Constant	Description
    CSS_CUSTOM	The value is a custom value.
    CSS_INHERIT	The value is inherited and the cssText contains "inherit".
    CSS_PRIMITIVE_VALUE	The value is a primitive value and an instance of the {{DOMxRef("CSSPrimitiveValue")}} interface can be obtained by using binding-specific casting methods on this instance of the CSSValue interface.
    CSS_VALUE_LIST	The value is a CSSValue list and an instance of the {{DOMxRef("CSSValueList")}} interface can be obtained by using binding-specific casting methods on this instance of the CSSValue interface.

Specifications

This feature was originally defined in the DOM Style Level 2 specification, but has been dropped from any standardization effort since then.

It has been superseded by a modern, but incompatible, CSS Typed Object Model API that is now on the standard track.
